USB-C to RS-232 Adapter with FTDI Chip

This adapter connects legacy DB-9 serial devices to a modern USB-C host. It uses an FTDI chip for reliable USB 2.0 data communication. The 5 ft cable includes LED indicators for link testing. It suits industrial tools, lab equipment and classic hardware that still rely on serial connections.

For Engineers Maintaining Serial Gear — Not

The reversible USB-C plug works only with USB-C sockets and cannot connect to USB-A without a separate hub. It supports Windows 7, 8, 10 and 11 plus Linux and MacOS 10.X. Buyers whose machines offer only USB-A ports should look at a different adapter.

FTDI Chipset Decides Driver Stability

The FTDI chip provides the serial-to-USB translation and determines driver behaviour across supported operating systems. ESD protection on the RS-232 I/O lines is rated at +-15KV. Verify that your application requires this chipset before purchasing.
